7 Best Looks from Our Favorite Holiday Movies

Holiday Shine: Reese Witherspoon in "Four Christmases" The holidays are all about sparkle and light, so why shouldn't your hair follow suit? Getting Witherspoon's killer shine starts in the shower, says Jeffrey Jagged, a stylist at the Cristophe Salon. "For this look, don't skimp on a fantastic shampoo and conditioner. Make it your early Christmas gift to yourself," Jagged says. Try R+Co Moon Shine Shampoo, $24, and conditioner, $25.

Prep wet hair with "just a dab" of straightening fluid, then blow the hair dry in a downward direction, using a large round brush. To get hair super sleek without "that dated stick-straight look," Jagged recommends straightening large sections of hair with a ceramic flat iron, "rock[ing] the iron inward at the ends."
